Goalkeeper Brad Guzan. Yes, he made a mistake at D.C. United, but he also made numerous great saves.

Centerback Miles Robinson, who has been the steadiest of the three men in the back going back into the preseason.

Centerback Michael Parkhurst, who must keep a close eye on Rogelio Funes Mori

Centerback Leandro Gonzalez Pirez, who needs to keep his cool after flirting with two yellow cards against Herediano.

Right wingback Mikey Ambrose, who will get his second consecutive start. He didn’t have the best game at D.C. United, but another start may do him well. There are also no right-footed wingbacks on the roster. A good friend suggested Tito Villalba come in at this spot. I’m not sure his defense is good enough to warrant trying him at a new position in front of 53,500. Ambrose will be in for Julian Gressel, who is doubtful.

Left wingback Brek Shea, who didn’t play well at all against D.C. United, but did show what he can do against Herediano. I don’t believe George Bello made the trip, and Ambrose is on the other side, so there aren’t any more options other than Gordon Wild, who has yet to make a start.

Defensive midfielder Eric Remedi, who must deny service to Funes Mori and Dorlan Pabon.

Defensive midfielder Jeff Larentowicz, who will come in for his experience.

Midfielder Darlington Nagbe, who will come in for Barco because I think Atlanta United is going to take a more defensive approach.

Midfielder Pity Martinez, who came off the bench at D.C. United.

Striker Josef Martinez, who has to play because Atlanta United needs at least one goal.
